That's implied, yes.
I'm only being semi serious. You'd need to pay for machining, extra welding and a external Wastegate. Better to do a dived dump like scotts talkin about, for the power and boost levels you're looking at that would be adequate.
So, if i go down to my local TMR office with my front plate and this form filled out with section 8 ticked "other" and write in something like "improved cooling", would i be able to get a slimline plate?
